Patent GB-276097-A (GB)
Title: Improvements in or relating to pendulum-controlled mechanisms
IPC: G04B15/10
Filed: 1926-06-02
Abstract: 276,097. Craig, E. E. June 2, 1926. Addition to 242,472, Escapements.-In a pendulumcontrolled escapement a rolling mass periodically releases an escape wheel and causes impulses to be imparted to the pendulum in both dirctions of swing. The pendulum A carries a rigid crosshead B having adjusting screws B', B<2>, the heads of which receive the impulses. A wheel G, driven by shaft G<1> and gear G<3> from any source of power, has four pairs of teeth and between each pair is a pocket which does not extend from side to side of the wheel G but only to one side, these pockets extending to opposite sides of the wheel alternately. A trigger lever E rigid with a weight E<2> and a detent H has a forked end E<4> which is a prolongation of a fixed sloping platform P. The detent H engages one of four arms of an escape member S rigid with the shaft G' and wheel G. Shafts T and V carry normally horizontal runways T<1>, V<1> rigid with counterweights T<3>, V<3> and upright. arms T<2>, V<2>. Leading from the top of the wheel G to these runways are runways R, R', one on each side. M and M<1> are guard-plates at the inner ends of the runways T<1>, V<1>. The rolling ball starts from the platform P and passes over the fork E<4> and into a pocket of the wheel G; the lever E is lowered and the detent H releases the member S. The latter and wheel G rotate counterclockwise, Fig. 1, and the ball is raised in the pocket, being held by the appropriate pair of teeth. At the top it rolls on to one or other of the runways R, R', say R, and on to runways T<1>, rocking the latter so that the arm T<2> hits the screw B<1> and gives an impulse to the pendulum. When the runway T<1> has lowered sufficiently the ball escapes under the guard M on to the platform P and the cycle is repeated, the next pocket in the wheel G delivering the ball on to the opposit side so that the pendulum is given an impulse in the opposite direction. In a modification the two runways R, R<1> converge to a common runway from which the ball passes over the forked end of the detent lever, the ball giving impulses during its passage to a vane fixed to the pendulum. By omitting one half of the runway and by discharging the ball always in the same direction, the pendulum may be given an impulse in one direction only, as in the parent Specification.

Title: Method and means for smoothing mobile films upon webs
IPC: D06B1/08
Filed: 1935-05-13
Abstract: In a process for equalizing and smoothing the coating on a coated web, e.g. paper, by a pressure fluid directed against the web, pressure is exerted over the entire width of the web transversely of its direction of travel and at <PICT:0456746/IV/1> <PICT:0456746/IV/2> <PICT:0456746/IV/3> right angles to the plane of the web.  Coating liquid from a vat 5 is applied to a web 3 travelling over a platform 1 by coating mechanism 4, e.g. brushes, rolls, or sprays, and is smoothed by fluid discharged under pressure from devices 6 fed by pipes 7, 8 from a compressor 11.  The "air-knife" 6, Fig. 2, comprises an outer tube 13 provided with a longitudinal slit 15 defined by flanges 16 and an inner perforated tube 14 which is supplied with the pressure fluid from each end 7. The pressure in the tube 13 may be equalized by providing apertures 15<1>, Fig. 3, which progressively increase in area from the point of intersection of the fluid.  Instead of the elongated slit 15, the fluid may be discharged through a series of perforations or discontinuous, inclined, or transversely disposed slits.  The "air-knives" may be oscillated longitudinally in known manner.  The pressure fluid may be air, heated or cooled or impregnated with a vapour such as alcohol and may be applied intermittently to the coating in making water marks on paper by varying the distribution of the coating.  The process may be applied in making tinted paper directly on a paper making machine.  Specification 12141/12, [Class 140], is referred to.

Filed: 1941-11-01
Abstract: 595,349. Wireless aerials. BRITISH THOMSON-HOUSTON CO., Ltd., and BOWEN, A. Nov. 1, 1941, No. 14109. [Class 40 (v)] Means for moving an aerial in a circular path without changing its orientation comprise a tubular member fixed at one end to a rotor, extending at an angle to the rotor axis, and carrying the aerial at its free end, the orientation of the aerial being maintained by a connecting-rod free to rotate within, and supported against lateral deflection by, the tubular member. In the apparatus shown, a dipole aerial 1, optionally with a reflector 2, is carried on the end of a tubular member 3 secured at its other end to a plate 4 attached to the tubular rotor of an electric motor, the axis of the member 3 being inclined to that of the rotor so that the aerial is moved in a circular path. To prevent change of orientation of the aerial, it is mounted on a tubular rod 6 carried in ball bearings in the member 3 and secured to the ballmember 14 of a universal joint located at. the intersection of the axes of the tube 3 and the rotor. The joint comprises a hollow member 13 attached to a tubular member 7 secured to the stator of the motor and formed with a spherical seating against which the ball is urged by a ring 15 under the action of a spring 16 which is held by a sleeve 17 in the tubular member 7. Rotation of the ball 14 is prevented by a pin 12 engaging in an aperture in the wall of the member 7. A coaxial transmission line to the aerial is formed by the tubular rod 6 and a central conductor 21, the portion A of which may be formed of an alloy capable of withstanding the bending stresses which occur at this region, such as cadmium copper or copper cobalt beryllium. The conductor 21 is connected to an extension 23, which terminates in a connection 24. The member 3 is balanced by a fin 19 and masses 20.

Abstract: 734,387. Cold-cathode tubes. NORTHROP AIRCRAFT, Inc. May 20, 1953, No. 14156/53. Class 39 (1). [Also in Group XL (c)] A glow tube comprises a pair of anodes 9, 10 and a cold cathode 8 positioned between them, all the electrodes lying in a common plane. The cathode surface is divided into two separate cathode glow areas with one area facing each anode. The cathode may consist of two spaced wires joined together electrically with a shield separating them, Fig. 2 (not shown); or a single wire may have a mica or other insulating sheet 12 inserted in a diametral slot at right-angles to the common plane; or a diametral layer of insulating paint may be applied so as to separate the glow surfaces on each side of a single wire, Fig. 1A (not shown). In all cases the purpose is to prevent the glow migrating into the region opposite a non- discharging anode, so that the tube may possess two definite stable states for use in a flip-flop circuit (see Group XL (c)). The filling may be neon at between 100 mm. and half an atmosphere and a trace of polyatomic gas may be added to decrease deionization time and promote triggering.

Title: Improvements in or relating to the control of an internal combustion engine or engines in a power plant
IPC: F02D39/02
Filed: 1940-09-18
Abstract: 543,916. Servomotor control of internal combustion engines. SULZER FRERES SOC. ANON. Sept. 18, 1940. No. 14329. Convention date, Sept. 21, 1939. [Class 135] In apparatus for the servomotor control of one or more internal combustion engines in a power plant there is provided an intermediate adjusting element (piston 18) which while being controlled by the main controller 22 can hold the adjusting member (two-armed lever 19) in intermediate step positions between the main step positions. The fuel pump 4 of an engine 1 is controlled by a governor 2 the tension of the spring 5 of which is altered by movement of a piston 6 by fluid controlled by a valve 7. The main controller 22 moves a contact segment 24 to electrically actuate valves 29 ... 32 which regulate the flow of air or other fluid to the piston 18 and to pistons 11 ... 13, Fig. 3, constituting the main adjusting elements. The pistons 11 ... 13 are progressively shorter in length and act on the lever 19 through a crosshead 14. The 0 and 1 positions of controller 22 correspond to the lowest speed of the engine, the load being switched in for position 1. The main stop positions correspond to positions 2, 4, 6, 8 of the controller 22, the corresponding pistons 11 ... 13 acting alone for positions 4, 6, 8, whilst the intermediate stop positions correspond to positions 1, 3, 5, 7 of the controller, in which positions the piston 19 also is actuated. Instead of driving a gearing 38, Fig. 1, the engine 1 may drive a generator 39, Fig. 5, the output of which is regulated by a servomotor 44, 45 controlled through a linkage 42, 43, and a resistance 46, 47, whereby the excitation of the generator is so arranged that the torque depends on the speed at which the device is set. A valve 48 may be disposed between the valve 44 and its casing and be operated against a spring 52 by fluid flowing in a pipe 51 under the control of an additional valve 50 controlled by the controller 22. By this means two different torque steps are provided for each speed setting of the engine. The Specification as open to inspection under Sect. 91 refers also to non-electrical means for operating the valves. This subject-matter does not appear in the Specification as accepted.
